Hand layup molding process, also known as contact molding, is the earliest and most widely used molding method in the production of resin based composite materials. Hand layup molding process is a molding method that mainly involves manual operation and less use of mechanical equipment. It uses unsaturated polyester resin or epoxy resin as the matrix material to bond reinforcement materials together. Although the hand layup molding operation is simple, it requires high operational skills from operators. It requires operators to have a serious work attitude, proficient operating skills, and rich practical experience. A comprehensive understanding of product structure, material performance, mold surface treatment, gel coat quality, glue content control, reduction and placement of reinforcing materials, uniformity of product thickness, and various factors affecting product quality is required.
